DETERMINATION OF THE FEASIBILITY OF USING SOUTHERN PINE VENEER LOG CORES AS POSTS FOR FENCING HIGHWAY PROJECTS

THIS STUDY WAS CONDUCTED FOR THE DEPARTMENT OF TRANSPORTATION OF GEORGIA TO EVALUATE SOUTHERN PINE VENEER LOG CORES USED FOR HIGHWAY FENSING. THE OBJECTIVES WERE TO: AND PENETRATION OF POSTS 3 TO 7 YEARS OLD. 2. STUDY EFFECTS OF CAPS IN PREVENTING POST TOP DETERIORATION FROM WEATHERING AND DECAY. 3. DETERMINE EFFECTS OF AIR SEASONING ON CHECKING, PRESERVATIVE RETENTION AND PENTRATION COMPARED WITH STEAM-VACUUM CONDITIONING. 4. PROVIDE RECOMMENDATIONS FOR FUTURE USE OF POSTS AND CAPS, AND SPECIFICATION CHANGES. POSTS IN SIX INTERSTATE PROJECTS WERE EXAMINED AND SOUNDED, AND TESTED FOR RESIDUAL PRESERVATIVE RETENTION AND PENETRATION. STEAM-VACUUM CONDITIONED AND AIR SEASONED POSTS WERE TREATED AND TESTED AT THE TREATING PLANT. IT WAS CONCLUDED THAT: 1. FEW POSTS DECAYED. 2. THE REQUIRED 0.50 INCH SAPWOOD WAS NOT PRACTICAL. 3. PRESERVATIVE RETENTION WAS TOO LOW. 4. AIR SEASONING DID NOT APPRECIABLY INCREASE PRESERVATIVE PENETRATION AND RETENTION. 5. CAPPED TOPS WERE NOT WEATHERED OR DECAYED. IT WAS RECOMMENDED THAT USE OF THE POSTS CONTINUE WITH A MINIMUM 0.25 INCH PENETRATION IN HARDWOOD FACES AND AN INCREASE IN CREOSOTE TO 8 POUNDS AND PENTACHLORAPHENOL TO 0.40 POUNDS BY ASSEY.
